Bug#840684: firebird3.0: Please add patch to add m68k platform support

[John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de>]

Source: firebird3.0
Version: 3.0.1.32609.ds4-6
Severity: normal
Tags: patch
User: debian-68k@lists.debian.org
Usertags: m68k

Hi Damyan!

The patch attached to this bug report adds platform support for m68k
which is one of the ports architectures we have in Debian.

This patch contains two patches which have been squashed into one patch
for convenience. Both patches have also been sent upstream and are
awaiting review [1]. The patches sent upstream also contain some
more explanation.

Since firebird-dev is a reverse dependency to Qt and therefore transitively
a large number of packages, it's very important for the m68k port to have
a working firebird3.0 package.

Thus, it would be very much appreciated if you could include the attached
patch in your next upload.

Thanks a lot,
Adrian
